Pear (Pyrus spp) is an important fruit crop, grown in all temperate regions of the world, with global production ranked after grape and apples among deciduous tree crops. A high-density linkage map is a valuable tool for fine mapping quantitative trait loci (QTL) and map-based gene cloning. In this study, we firstly constructed a high-density linkage map of pear using SNPs integrated with SSRs,...
The present study describes a new set of 61 polymorphic microsatellite markers for beans and the construction of a genetic map using the BAT93 x Jalo EEP558 (BJ) population for the purpose of developing a reference linkage map for common bean (Phaseolus vulgaris). The main objectives were to integrate new microsatellites on the existing framework map of the BJ population, and to develop the fir...
MOTIVATION Current high-throughput sequencing technologies allow cost-efficient genotyping of millions of single nucleotide polymorphisms (SNPs) for hundreds of samples. However, the tools that are currently available for constructing linkage maps are not well suited for large datasets. Linkage maps of large datasets would be helpful in de novo genome assembly by facilitating comprehensive geno...
Eucommia ulmoides is an economically important tree species for both herbal medicine and organic chemical industry. Effort to breed varieties with improved yield and quality is limited by the lack of knowledge on the genetic basis of the traits. A genetic linkage map of E. ulmoides was constructed from a full-sib family using sequence-related amplified polymorphism, amplified fragment length po...
جنس کلئوم متعلق به خانواده کور (capparaceae) می باشد. در بررسی این جنس در خراسان 7 گونه یافت شده است . تاکساهای مذکور به منظور تعیین ویژگیهای تشریحی مورد مطالعه قرار گرفتند. هدف دیگر این پژوهش مطالعه جنس کلئوم با استفاده از روش تاکسونومی عددی می باشد. داده ها (ویژگیهای تشریحی) توسط سه روش تجزیه ای خوشه ای complete linkage, single linkage, average linkage آنالیز شدند. نتایج این بررسی مطالعات تاک...
The objective of this project was to integrate the currently available linkage maps for bovine chromosome 7 (BTA7) by combining data sets from eight research groups. A total of 54 unique markers were typed in eight pedigrees. Multilocus linkage analysis with CRI-MAP produced a bovine chromosome 7 consensus framework map of 27 loci ordered with odds greater than 1000:1. Furthermore, we present a...
Inaccurate genetic (or linkage) maps can reduce the power to detect linkage, increase type I error, and distort haplotype and relationship inference. To improve the accuracy of existing maps, I propose a meta-analysis-based method that combines independent map estimates into a single estimate of the linkage map. The method uses the variance of each independent map estimate to combine them effic...
In the past, a classical map of the tomato genome has been established that is based on linkage data from intraspecific Lycopersicon esculentum crosses. In addition, a high density molecular linkage map has recently been constructed using a L. esculentum x L. pennellii cross. As the respective maps only partially match, they provide limited information about the relative positions of classical ...
